Adding a custom domain to ProtonMail is a straightforward process that allows users to personalize their email address and enhance their brand identity. To begin, users must first purchase a domain from a domain registrar. Once this is done, the user can navigate to the ProtonMail settings and select the "Domains" tab.
From there, they can click on the "Add Custom Domain" button and enter their purchased domain. The next step involves verifying ownership of the domain by adding a TXT record to the DNS settings. Once this is completed, the custom domain will be successfully added to ProtonMail, providing users with a professional and distinctive email address.
